"Anticipating a storage crunch spurred by big data, IBM and Fujifilm are advancing the state of art in magnetic tape with a prototype capable of storing 85.9 billion bits of data per square inch," writes Joab Jackson
in
InfoWorld.

"IBM and Fujifilm have demoed a 154TB LTO-size tape cartridge which
could come to market in 10 years' time.

While it falls short of the Sony 185TB development, it should, with
IBM's tape partnerships, see Sony exit the field.

The Sony development involved a 148Gbit/in^2 tape density and its own
tape design to achieve a 185TB uncompressed capacity. IBM has been
working with Fujifilm to extend today's Barium Ferrite (BaFe) tape
particle technology to achieve 85.9Gbit/in^2..."

"The LTO Program Technology Provider Companies (TPCs), HP, IBM and Quantum, announced that LTO generation 6 tape has reached a cost-per-gigabyte of 1.3 cents based on the current market price of tape media. (Assuming LTO-6 cartridge price of $80 based on a pricing survey of more than two dozen websites offering LTO-6 cartridges and assuming 2.5:1 compressed capacity of a single cartridge. Actual prices may vary.).."
